Help - what types of images/art would go well with this piece

[Stigohlsson]

Trying to get some ideas on how to complete this half sleeve.  The work you see is, in part, a cover up (old tribal band); I like it but not sure on what types of imagery would supplement the piece as part of a half sleeve project.  Any thoughts, insight(s), or ideas are much welcomed.

A closer, more detailed pic might help everyone see what's going on.  It looks like a dark theme and that should be easy to expand depending on your taste.  Are you going to the same artist that did that piece?  Have you asked their opinion?

Welcome too!
